Title: Improvements in or relating to Ordnance Breech Mechanism.
Inventor: ASBURY DORSEY FROST
IPC: F41A3/04
Filed: 1917-06-11
Abstract: 107,582. Asbury, D. F. June 13, 1916, [Convention date]. Ordnance breech mechanism.-Relates to the screw type having a carrier swing- ing about a horizontal transverse axis, and consists in providing a spring acting between the carrier and the gun to counterbalance the moment due to the weight of the breech mechanism. In the form shown in Fig. 2, the spring 18 is housed in a cylindrical cavity 10 in the breech screw carrier C and exerts at its top end a force producing a constant closing moment about the axis c of the carrier. At the bottom end, the spring abuts against a piston 15, fitted with anti-friction rollers 17 engaging the wall of the cavity 10, and connected by a swinging link 21 with a fixed bracket 20 on the gun. The spring due to the thrust of the link 21 therefore exerts at its bottom end a resultant force on the carrier in a plane through the rollers 17 at right-angles to the axis of the spring. This force acts during the first part of the opening movement to produce a closing moment which gradually diminishes to zero, after which an opening moment is exerted. The resultant moment exerted on the carrier by both ends of the spring serves to counterbalance the moment due to the weight of the breech mechanism. A handle 14 facilitates manual operation of the carrier. Fig. 5 shows the invention applied to breech mechanism fitted with an air pressure piston-and-cylinder device 25', 22 for closing the carrier, the air under pressure being supplied through the hollow pistonrod by a flexible pipe 29. Specification 101,716 is referred to,

Title: Improvements relating to the use of false twisting mechanisms in textile machines
Inventor: SCRAGG ERNEST PHILLIP RUSHTON
IPC: D02G1/02
Filed: 1956-03-17
Abstract: 809,606. Twist tubes; crimping yarns. SCRAGG & SONS Ltd., E. March 4, 1957 [March 17, 1956], No. 8400/56. Classes 120(2) and 120(3) A crimped yarn wherein the effect of torque, induced by setting false twist, is obviated, is produced by passing the yarn through the twist tube of a false twisting mechanism and rotating the tube alternately in one direction and then the other. As shown, a twist tube 1, which is rotatably mounted at the end of one arm 2 of a bell crank lever, is located between a pair of endless driving belts 3, 4 which run in the same direction. The other arm 5 of the lever is slotted at 6 to accommodate a pin 7 projecting from a rod 8, which is reciprocated by a cam or solenoid mechanism to bring the tube 1 into contact with one or other of the belts 3, 4 so that the tube rotates firstly in one direction and then in the other. A brake pad may be disposed between the belts momentarily to contact the twist tube when it is out of contact with the belts so as to arrest it. The cam or solenoid mechanism can be so adjusted that contact of the tube with the belts takes place for equal lengths of time so that the mean residual torque in the whole yarn is zero.
